如何調用 Powershell 腳本並從 C# windows 表單傳遞參數

Question

我想調用 powershell 腳本，它接受來自 c# windows 表單的一些參數。

例如：- 我有 powershell 腳本，它接受 2 個參數，我有一個 windows 表單，帶有兩個文本框和一個提交按鈕。 我想從這兩個文本框中將參數傳遞給 powershell 腳本。 當我按下提交按鈕時，它將調用 powershell 腳本並在 powershell 終端上運行它，並在 powershell 終端上顯示結果。

Answer 1

這是 powershell 腳本的工作示例，它為您提供 char 的 ASCII 代碼。 假設您有 richTextbox1 用於顯示腳本的 output 並且您有 button1 觸發它運行 - 這是代碼：

        public void RunPowershell()
        {
            var ps1File = @"C:\asc.ps1";

            ProcessStartInfo startInfo = new ProcessStartInfo();
            startInfo.FileName = @"powershell.exe";
            startInfo.Arguments = $@"& '{ps1File}' f";
            startInfo.RedirectStandardOutput = true;
            startInfo.RedirectStandardError = true;
            startInfo.UseShellExecute = false;
            startInfo.CreateNoWindow = true;
            Process process = new Process();
            process.StartInfo = startInfo;
            process.Start();

            string output = process.StandardOutput.ReadToEnd();
            string errors = process.StandardError.ReadToEnd();

            richTextBox1.Text = $"Output: {output}{Environment.NewLine}Errors = {errors}";
        }

        private void button1_Click(object sender, EventArgs e)
        {
            RunPowershell();
        }

這將為 char 'f' 提供 ascii 代碼。

Bellow 是附在示例中的 PS 腳本：

function Syntax {
    Write-Host
    Write-Host "Asc.ps1,  Version 1.00"
    Write-Host "Returns the numeric ASCII value for the specified character"
    Write-Host
    Write-Host "Usage:   " -NoNewline
    Write-Host "ASC.PS1  char" -ForegroundColor White
    Write-Host
    Write-Host "Returns: Numeric ASCII value of " -NoNewline
    Write-Host "char" -ForegroundColor White
    Write-Host
    Write-Host "Notes:   The ASCII value is written to Standard Output (usually the screen)"
    Write-Host "         as well as returned as `"errorlevel`""
    Write-Host "         If more than 1 character is passed on the command line, only the first"
    Write-Host "         character will be used, the remainder of the string will be ignored."
    Write-Host "         The `"errorlevel`" will equal the ASCII value, or 0 if no parameter"
    Write-Host "         was passed, or -1 in case of errors or for this help"
    Write-Host
    Write-Host "Credits: Code to pass exit code as `"errorlevel`" to the calling batch file"
    Write-Host "         or PowerShell script by Serge van den Oever:"
    Write-Host "         weblogs.asp.net/soever/returning-an-exit-code-from-a-powershell-script" -ForegroundColor DarkGray
    Write-Host
    Write-Host "Written by Rob van der Woude"
    Write-Host "http://www.robvanderwoude.com"

    $Host.SetShouldExit( -1 )
    Exit
}

if ( $args.Length -eq 1 ) {
    if ( $args[0] -eq "/?" ) {
        Syntax
    } else {
        $input = $args[0]
    }
} else {
    Syntax
}

if ( $input -eq "" ) { $input = [string][char]0 }

[char]$char = $input[0]

Write-Host ([byte]$char) -NoNewline

# Pass exit code to calling batch or PowerShell script, by Serge van den Oever
# https://weblogs.asp.net/soever/returning-an-exit-code-from-a-powershell-script
$Host.SetShouldExit( [byte]$char )
Exit

將其保存到磁盤C ，將其命名為asc.ps1 --> 你就有了工作示例。

Answer 2

只需啟動帶參數的 powershell.exe

要啟動任何外部應用程序，您可能需要檢查 Process 的工作方式。
